DeepObservatory

Effortlessly propagate ObservableObject changes within a published list.

Works transparently in the background and avoids dirty workarounds like ObservableArray that require large refactorings afterwards.

Installation

Add the following repository using Swift Package Manager:

https://github.com/Quintschaf/DeepObservatory.git

Usage

import DeepObservatory

class World: ObservableObject {
    @Published var people: [Person] = [] {
        didSet { self.observe(people) } // magic
    }
}

class Person: ObservableObject, Identifiable {
    @Published var id = UUID()
    @Published var name: String
    @Published var age: Int
}

Usually, changes to a Person in people would not trigger an update on either people or World.
DeepObservatory takes care of observing and propagating these changes with minimal effort.

Restrictions

DeepObservatory can only observe lists of objects implementing ObservableObject & Identifiable.
